Wood Meets Metal
The K3 HE combines the elegance of natural wood with a precision metal frame, creating a look that feels both refined and powerful. The contrast of warm wood texture and sleek metal craftsmanship delivers a premium balance of natural beauty and modern performance.

Ultra-slim
Featuring an ultra-thin 12.1mm low-profile switch, the K3 HE achieves a sleek front edge profile of just 22.0mm. This makes the wooden body K3 HE one of the thinnest wireless mechanical keyboards in the world, while still delivering a distinguished tactile response.

SUPER SENSITIVE & FAST RESPONSE

Keychron ULTRA-FAST LIME LOW-PROFILE MAGNETIC SWITCH
The Keychron K3 HE comes with pre-lubed Keychron Ultra-fast Lime Low-Profile magnetic switches for an ultra-stable and ultra-responsive typing experience with an industry-leading, lightning-fast response time and precise control over the way your keyboard feels and responds. Made from POM material, it delivers an incredibly satisfying, soft, and thocky typing sound, enhancing every keystroke for a more enjoyable typing experience.

ADJUSTABLE ACTUATION POINT
Customize each key with precision, adjusting actuation points from 0.2 to 2.9 mm with 0.1 mm sensitivity. Set shallow keypresses for instant actions and deeper ones for deliberate engagement, minimizing accidental touches and giving you an edge in both gaming and typing.


Last Key Priority (LKP) & Snap Click
LKP allows seamless directional changes by prioritizing the last key pressed, ensuring smoother gameplay in titles like Valorant. With Snap Click, deeper keypresses take precedence when two keys are hit at once, automatically resetting shallower presses.
*They are disabled by default, but you can easily enable them in our Launcher web app when needed.
one key. multiple commands
Assign four actions to a single key based on the depth of your press. For example, lightly press a key to walk forward in a game, and press deeper to run. Additionally, releasing the key also supports two-stage settings. This allows for smoother, personalized combinations that can give you an edge in competitive gaming.

Dynamic rapid trigger
Activate or deactivate keys based on how far they travel, not predefined points. This means immediate key reactions—press to activate, release to reset—allowing for faster, more precise keystrokes. In rapid gameplay, this translates to executing complex actions in real-time without delay, giving you a serious advantage during fast-paced sequences.

Analog mode
Experience the power of Analog Mode on your K3 HE, bringing game controller-like precision to your keyboard. This mode enables variable inputs instead of the usual on/off signals, letting you achieve more fluid and dynamic control.
With each keypress, the K3 HE detects how far you press, translating it into different speeds and intensities. Enjoy nuanced control and heightened responsiveness in racing games, sports simulations, and more.





2.4 GHz & Bluetooth Connection
Experience peak gaming performance on the fly with the K3 HE's 2.4 GHz wireless connection boasting a rapid 1000 Hz polling rate. For seamless multitasking across your computer, phone, and tablet, you can effortlessly connect the K3 HE via Bluetooth 5.2 to three devices.


AN EPIC CORE INSIDE THE KEYBOARD
Engineered with a powerful chip (MCU), 256K flash, and QMK open-source firmware to provide more flexibility for developers. The polling rate is 1000 Hz out of the box in Type-C wired mode and 2.4 GHz mode, which greatly helps when competitively gaming.
SMOOTHER, FASTER, MORE SATISFYING

Customize Every Part
To build a fully customizable keyboard, we designed every component to be easy to assemble. Therefore, you can customize and adjust each component as you wish.
KEYCAPS The low-profile double-shot PBT keycaps on the K3 HE provide excellent resistance to oil and prevent legends from fading over time.
FRAME Combines natural wood accents with aluminum side frames, bringing natural elegance to a lightweight yet durable construction while ensuring a comfortable typing experience.
SWITCHES Enhance your typing experience with a combination of high-quality acoustic foams, including sound-absorbing foam and latex.
PLATE Made from CNC-machined aluminum, it provides essential structural support, stabilizing the switches, influencing typing feel and sound, while ensuring durability.
SOUND-ABSORBING FOAM The sound-absorbing foam helps reduce echo and unwanted typing noise, delivering a cleaner sound profile.
PCB The printed circuit board that registers keystrokes; hot-swappable versions allow for easy switch replacement.
SILICONE BOTTOM PAD + PET FILM The bottom pad and PET film provide protection against short circuits, shield the interior from dust and scratches, and offer additional dampening.
BOTTOM CASE ACOUSTIC FOAM Soft foam that helps reduce vibrations and noise while providing a cushioned typing feel.
BOTTOM CASE A lightweight, rigid polymer body that ensures easy portability and a more muted typing experience.

SUITABLE FOR ALL DEVICES
Offers a Mac layout while remaining compatible with Windows. It stands out in the market by providing the same multimedia and function key functions as Apple keyboards for Mac users, but with enhanced tactile feedback.


Low-Profile Double-Shot PBT Keycaps
Designed for a premium typing experience, the K3 HE features our unique double-shot PBT keycaps, offering excellent durability and oil resistance for long-term use.
HOT-SWAPPABLE
Unlike mechanical switches, which depend on physical contact, magnetic switches use magnets to detect key presses. You can easily swap out every Keychron Ultra-fast Lime Low-Profile magnetic switch in seconds—no soldering required.

Unlock Dynamic Backlit Control
Go beyond standard presets with 22+ RGB backlight settings — including a static white option. Our advanced lighting engine includes two powerful features to fuel your creativity: Per-key RGB and Mix RGB. You can further fine-tune and remap keys with ease, crafting your unique style with vivid, dynamic RGB control.


Per-key RGB
With Per-key RGB, every single key is a digital brushstroke. This feature lets you individually customize the color of each key, transforming your keyboard into a vibrant canvas.
Mix RGB
With Mix RGB, you can split your keyboard into two custom lighting zones, each with unique effects. Create creative, high-contrast combinations to make your entire setup pop with vibrant style.
